Anyone Know of Large Serial Port Splitter

Greetings,
An answer I made to another post reminded me of something I have been looking for for a while...
Does anyone know of a larger serial port splitter? Something around 1x8 with RS-232 ports.
I am not looking for the router/manageable type, just one that passes all data bi-directionally.
Thanks.

These guys may have what you need.

Unfortunately, this is a one-way device, typicaly used for DMX control of lighting systems. I need data back from the devices.
B & B Electronics only has a 1x2 splitter, unless you get into managaed routers.
Sounds like an Axcent3 to me!
I was considering that, but I need quite a few. If the Axcent 3s would be controllable, they would suck up 14 Axlink channels a piece. To run them as masters with an Axcess program making them do what I need seems a bit unreliable.
Nice thought though!
Just curious...so what you are looking for is to turn one port, say on a NI-700 into 8 ports? How would Netlinx no how to address the 8 different pieces of hardware?
Just a nOOb question...
Have you looked at the all the Ethernet to RS232 devices out there as an option?
They are about $100.00 per port.
Cheap. I have a load of flat screens for a restaurant that are all addressable 1-32. A simple splitter/combiner would fit the bill. I cannot beleive it is so hard to find one.

Now there's a good idea! Better yet, 422 cascaded to a convertor on each set.
I've used about ten of these, and have had good experience with them:

Less than $100 per port. You can bridge ports together via Ethernet with up to max eight clients per port on the PS810. You could tie seven ports in one box to seperate port in same box. They also work quite well as serial port expanders. For lowest latency use UDP on a dedicated VLAN. I've even used them for camera PTZ control with very acceptable results.
This product series would do what you need, as they support up to 32 client connections per port:

For both series each port can be configured as client or host. You would set master port as host, then setup the other required number of ports to connect to the master port. All within the same box.
